I do manual upvotes only for this reason. I also check accounts's activities and wallets. I'm not a role model by any means, but I do like to support accounts that focus on providing value as opposed to those who search for ways of cracking the game or whatever. Some might find formulas for vote/follower farming, but they'll only work for so long. Less HIVE gets created every 250,000 blocks and one day, the only ways of getting it will be to run nodes or provide a service that someone is willing to pay you in HIVE or HBD for.
Well, author rewards will still always pay some HP, but yes a lot less than they do now.
